44 Feet Dipole. Where is the Truth?

 

a well designed and well built antenna tunerplus a good quality SWR meter. 44 feet, when converted to meters will give you a length of 13.41 meters overall, or 6.70 meters for each leg.Likewise, the 88 feet overall length is 26.82 meters of 13.41 meters on each leg...

 

(Figure 2 shows the 88- Feet Dipole Antenna.)

 

Note I.G.: It is very, very sophisticated and old question Ė what optimal length for a wave ham antenna is. We may found lots different antennas and lots different way to match the antenna with a feed line. However, letís simulate the input impedance of the antenna with help MMANA. Below you can see SWR (at 350- Ohm Terminal) for 44 feet Antenna placed at 10 and 20- meters above real (simulated by MMANAof course) ground. As you can see the 44- feet antenna really has at the amateur bands SWR/Impedance that could be matched with simple ATU.
